I don't mind having a GOOD non-ringed set-up, but when it's worn out, it's worn out and nothing I can do about it. It's a matter of principle because I've never really had too much issues with that, it's just the peace of mind in the back of my head that says, nah, I'll have the ringed one...
I don’t choose ABC/AAC for balls-out power. That’s never been the issue. I have had many ringed engines, and they ran fine. But the just weren’t as good as the ringless engines. Lapped included. I love the lapped engines just as much as ABC engines. Ringed diesels are not the best - and I have converted several engines to diesel. The ringless engines are far easier to start, and don’t suffer from stuck rings due to carbon. I’ll say this; I know who to turn to when I have ringed engines to dump.

Joking aside - ringed engines have their place. In the displacement size I use, it makes little sense to have ringed engines (mostly <10cc with the exception of a few 4-strokes and an ST S90 that are used on airboats and a couple ancient Enya 2-strokes).
